The mechanisms through which mutations in splicing factor genes drive clonal hematopoiesis (CH) and myeloid malignancies, and their close association with advanced age, remain poorly understood. Here we show that telomere maintenance plays an important role in this phenomenon. First, by studying 454,098 UK Biobank participants, we find that, unlike most CH subtypes, splicing-factor-mutant CH is more common in those with shorter genetically predicted telomeres, as is CH with mutations in PPM1D and the TERT gene promoter.

Background: Perturbed lipid metabolism in cellular environment plays an essential role in the progression of peripheral neuropathy, such as Charcot-Marie-Tooth disease type 1A (CMT1A). Current deep-profiling of lipidome still has certain limitations for high-throughput analysis of clinical samples, such as low sensitivity, extensive requirement of instrument modification, technician-dependent pretreatment and lack of method-adapted data-processing software.

Results: Herein, a new generation aza-Prilezhaev aziridination (APA) reagent has been designed for coupling with high-resolution liquid chromatography mass spectrometry (LC-MS) to conduct comprehensive untargeted deep lipidomics of CMT1A disease.

The Chatbot Assessment Reporting Tool (CHART) is a reporting guideline developed to provide reporting recommendations for studies evaluating the performance of generative artificial intelligence (AI)-driven chatbots when summarizing clinical evidence and providing health advice, referred to as Chatbot Health Advice (CHA) studies. CHART was developed in several phases after performing a comprehensive systematic review to identify variation in the conduct, reporting and methodology in CHA studies. Findings from the review were used to develop a draft checklist that was revised through an international, multidisciplinary modified asynchronous Delphi consensus process of 531 stakeholders, three synchronous panel consensus meetings of 48 stakeholders, and subsequent pilot testing of the checklist.

Introduction: Obtaining a driver's license enhances independence and quality of life but can be challenging for adolescents with health conditions. Health conditions may impact driving behavior and not always require driving restrictions. Strategies that promote safe independent driving for adolescents with various health conditions are not well described.

Mapping spatiotemporal dynamics of crop-specific areas is of great significance in addressing challenges faced by agricultural systems. But comparable multi-phase crop maps in year series have not yet been developed in most regions of the global. In this study, we developed a framework for updating annual crop-specific area maps at 10 km resolution based on crop statistics disaggregating, multi-source data integrating and machine learning.

Developing mechanically robust hydrogels with low ice adhesion and anti-icing durability in low-temperature environments (≤ -20 °C) remains a persistent challenge. In this study, a dual-network organohydrogel (PAD) was synthesized through a facile one-pot copolymerization of acrylamide (AM), and [2-(Methacryloyloxy)-ethyl]-trimethylammonium chloride (DML) dissolved in poly-(vinyl alcohol) (PVA) aqueous solution, followed by solvent exchange in a mixed solvent of dl-1,2-Isopropylideneglycerol-(ACM) and water (HO). This unique solvent exchange enhances chain entanglement within the interpenetrating dual networks and establishes robust hydrogen bonding interactions.

Background: When using a dataset to develop or update a clinical prediction model, small sample sizes increase concerns of overfitting, instability, poor predictive performance and a lack of fairness. For models estimating the risk of a binary outcome, previous research has outlined sample size calculations that target low overfitting and a precise overall risk estimate. However, more guidance is needed for targeting precise and fair individual-level risk estimates.

NPM1 is a multifunctional phosphoprotein with key roles in ribosome biogenesis among its many functions. NPM1 gene mutations drive 30% of acute myeloid leukemia (AML) cases. The mutations disrupt a nucleolar localization signal and create a novel nuclear export signal, leading to cytoplasmic displacement of the protein (NPM1c).

Background: Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common form of CMT, varying from asymptomatic to severe. The aim of this study was to investigate whether the diffusion tensor imaging (DTI) parameters and diameter of the proximal nerves, as measured by magnetic resonance neurography, can be used as a potential marker to reflect the progression.

Methods: This was a prospective study including 45 consecutive patients with CMT1A, divided into three subgroups by foot dorsiflexion muscle strength: mild cases (Group 1), moderate cases (Group 2), and severe cases (Group 3).

Digital health technologies (DHTs), including those incorporating artificial intelligence (AI), have the potential to improve healthcare access, efficiency, and quality, reducing gaps between healthcare capacity and demand. Despite prioritisation in health policy, the adoption of DHTs remains limited, especially for AI, in part due to complex system requirements. Target product profiles (TPPs) are documents outlining the characteristics necessary for medical technologies to be utilised in practice and offer a way to align DHTs' research and development with health systems' needs.

Rigorous study design and analytical standards are required to generate reliable findings in healthcare from artificial intelligence (AI) research. One crucial but often overlooked aspect is the determination of appropriate sample sizes for studies developing AI-based prediction models for individual diagnosis or prognosis. Specifically, the number of participants and outcome events required in datasets for model training and evaluation remains inadequately addressed.
